Hello Kjeld, sorry for the long delay .. I haven't delved into it just yet. But - I do have some info you may find useful on disassembly of the original Pentax Q: https://kayakfari.wordpress.com/ph ...

I have a similar 220 degree circular fisheye in 12mm board mount that I'd like to work with the Q. Like you, I quickly discovered that it has an ultra short flange focal distance. This means that ...

Yes that would be interesting to know. The phosphors are maybe half a millimeter? Here are the facts: Pentax Auto Bellows M fully extended + 36mm tube Spiratone 35mm 3.5 enlarger lens (at f/8) Pent ...
